FIG. 1 illustrates a structure of a mobile terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 1, a Radio Frequency (RF) unit 123 provides radio communications for the mobile terminal. The RF unit 123 includes an RF transmitter (not shown) for frequency up-converting of transmission signals and amplifying the up-converted signals, and an RF receiver (not shown) for low-noise-amplifying of received signals and frequency down-converting the amplified signals. A data processor 120 includes a transmitter for encoding and modulating the transmission signals, and a receiver for demodulating and decoding the received signals. In other words, the data processor 120 may include a modem and a codec. The codec includes a data codec for processing packet data, and an audio codec for processing audio signals such as voice or other similar audio signals. An audio processor 125 plays received audio signals output from the audio codec of the data processor 120 using a speaker SPK, and transfers transmission audio signals picked up by a microphone MIC to the audio codec in the data processor 120.

A key input unit 127 includes keys for inputting numeric and text information and function keys for setting various functions. However, the present invention is not limited thereto, and the mobile terminal may include a touchscreen or other similar elements for inputting numeric and text information.

A memory 130 may include a program memory and data memory. The program memory may store programs for controlling the general operation of the mobile terminal. The data memory may temporarily store the data generated during execution of these programs. The memory 130 may store information about types of executable applications, associated with types of touch events.

According to the present exemplary embodiment of the present invention, the memory 130 may store a control program for displaying a separate screen window for running an application according to a type of a touch event having occurred on the touch screen so as to run the application. The memory 130 may store a control program for hiding the screen window in response to a touch event that has occurred in an external area of the screen window while the separate screen window for running an application is displayed, and displaying the screen window if the touch event is terminated.

A controller 110 controls the overall operation of the mobile terminal. The controller 110 displays a screen window for running an application according to a type of a touch event having occurred on the touch screen so as to run the application, and hides the screen window in response to a touch event that has occurred in an external area of the screen window while displaying the screen window. The controller 110 may display a separate window by overlapping the screen window for running the application on the current screen. In other words, the controller 110 may display the application in a separate window that is displayed on top of other windows of the screen window.

While displaying the screen window for running the application according to the type of the touch event having occurred, if a touch event occurs on the screen window, then the controller 110 exits, i.e., stops displaying, the screen window on which the touch event has occurred, and displays a screen window for running an application corresponding to the type of the touch event having occurred.

While displaying the screen window for running the application according to the type of the touch event having occurred, if a touch event occurs on the screen window, then the controller 110 displays a list of applications, exits the screen window on which the touch event has occurred, and then displays a screen window for running an application selected from the list of applications displayed by the controller 110. If the touch event that occurred in an area of the screen other than the screen window for running the application is terminated due to a type of the touch event, then the controller 110 displays the screen window.

While hiding the screen window for running the application according to the type of the touch event having occurred, if an application is selected on the current screen by a drag event that occurred while the touch event is maintained, then the controller 110 stores data executed on the screen window as data for the application selected by the touch and drag events, and at the same time, stops displaying the hidden screen window.

While hiding the screen window for running the application according to the type of the touch event having occurred, the controller 110 updates the application. The controller 110 may update only synchronizable applications, and may update the applications only if their synchronization time is longer than a time period from the time the screen window was displayed till the time the screen window was hidden. However, the present invention is not limited thereto, and the controller 110 may update applications in any suitable manner.

While displaying the screen window for running the application according to the type of the touch event having occurred, the controller 110 may update the application, or the controller 110 may update the application when the screen window is exited or no longer displayed.

The controller 110 may display the screen window for running the application in a semi-transparent manner depending on the type of the touch event having occurred. When the screen window is displayed in a semi-transparent manner, the user may run the application in the semi-transparent screen window while viewing the contents displayed on the background screen. As to a user's input action occurring on the activated semi-transparent screen window, the action is performed only on the screen window without affecting the background screen or the items, elements or applications displayed on the background screen. While displaying the screen window for running the application according to the type of the touch event having occurred, if an exit button or key is selected or an exit command input on the screen window, then the controller 110 stops displaying the screen window for running the application.

A camera 140 includes a camera sensor for capturing images by capturing an optical image signal and converting the captured optical image signal into an electrical signal that may be an analog image signal or a digital image signal. The camera 140 also includes a signal processor for converting the analog image signal captured by the camera sensor into digital data. The camera sensor may be a Charge-Coupled Device (CCD) or Complementary Metal-Oxide-Semiconductor (CMOS) sensor, and the signal processor may be implemented with a Digital Signal Processor (DSP). However, the present invention is not limited thereto, and the camera sensor and the signal processor may be implemented in any suitable manner. The camera sensor and the signal processor may be implemented either in an integrated way, or in a separated way.

An image processor 150 performs Image Signal Processing (ISP) for displaying the image signals output from the camera 140 on a display 160. The ISP performs functions such as gamma correction, interpolation, spatial variations, image effects, image scaling, Automatic White Balance (AWB), Automatic Exposure (AE), and Automatic Focus (AF), and other similar image processing operations and functions. The image processor 150 processes the image signals output from the camera 140 on a frame-by-frame basis, and outputs the frame image data according to characteristics and a size of the display 160. The image processor 150 includes a video codec, which compresses the frame image data displayed on the display 160 according to a preset coding scheme, and decompresses the compressed frame image data into the original frame image data. The video codec may include a Joint Photographic Experts Group (JPEG) codec, a Moving Picture Experts Group 4 (MPEG4) codec, a Wavelet codec, or any other similar video codec. The image processor 150 includes an On-Screen Display (OSD) function, and may output OSD data according to the size of the screen displayed under control of the controller 110.

The display 160 includes a screen (not shown) for displaying image signals output from the image processor 150 and user data output from the controller 110. The display 160 may be a Liquid Crystal Display (LCD), an Organic Light Emitting Diode (OLED) display, or any other suitable display type. In the case of the LCD, the display 160 may include an LCD controller, a memory capable of storing image data, and an LCD panel. When the screen of the display 160 is implemented in as a touch screen, the LCD or other suitable display type may serve as an input unit. In this case, keys such as the key input unit 127 may be displayed on the display 160.

In accordance with the present exemplary embodiment of the present invention, the display 160 displays a separate window by overlapping the screen window for running the application on the current screen according to the type of the touch event having occurred to run the application.

The operation of running an application in a mobile terminal will be described in detail below with reference to FIGS. 2A to 7B.

FIGS. 2A and 2B illustrate a process of running an application in a mobile terminal according to an exemplary embodiment of the present invention.

Referring to FIGS. 1, 2A and 2B, if a touch event to run an application occurs in the mobile terminal in step 201, then, in step 202, the controller 110 determines a type of the touch event having occurred and displays a screen window A for running an application according to the type of the touch event having occurred. In step 202, the controller 110 determines a type of the application corresponding to the type of the touch event having occurred using the memory 130, and then displays a separate window by overlapping the screen window A for running the detected application on the current screen of the display 160.

The type of the touch event may be determined according to the number of touch inputs and the touch input time, i.e., an amount of time for which the touch input occurs. In a case where a stylus pen is used, the type of the touch event may be determined according to the number of touch inputs and the touch input time, which occur when a button mounted on the stylus pen is input or pressed.

While displaying the screen window A in step 202, the controller 110 determines, in step 203, whether a touch event to run an application occurs in an area of the screen window A. If a touch event occurs on the screen window A, then, in step 204, the controller 110 determines a type of the application corresponding to the type of the touch event having occurred using the memory 130, stops displaying the screen window A, and displays a separate window by overlapping a screen window B for running the detected application on the current screen.

Although not shown in FIG. 2, while displaying the screen window A in step 202, if a touch event to run an application occurs in an area of the screen window A, the controller 110 may display a list of applications, and if an application is selected from the application list, the controller 110 may exit the screen window A and display a separate window by overlapping a screen window for running the selected application on the current screen.

While displaying the screen window A in step 202, the controller 110, in step 205, determines whether a touch event occurs in an external area of the screen window A. If a touch event occurs in an external area of the screen window A, then the controller 110 hides the screen window A by inactivating it in step 206. A type of the touch event for hiding the screen window A by inactivating it may be a variety of touch input actions. Therefore, the screen window A is hidden while the touch input action is maintained in then external area of the screen window A, so that the user may view the contents on the background screen of the screen window A.

While hiding the screen window A in step 206, the controller 110, in step 207, determines whether the touch event is terminated, i.e., the touch input is not maintained. If so, then in step 208, the controller 110 displays again the screen window A on the current screen by activating it. In steps 205 to 208, by repeating the displaying and hiding of the screen window A in response to the touch event, the user may run the application on the screen window A while viewing the contents on the background screen of the screen window A.

If the touch event having occurred is maintained in step 207 while the screen window A is hidden in step 206, then the controller 110 determines whether a drag event occurs in step 209. If a drag event occurs, then in step 210, the controller 110 determines whether an application is selected by the touch and drag events. If an application is selected by the touch and drag events, the controller 110 stores the data executed on the screen window A as data for the application selected by the touch and drag events and exits or stops displaying the screen window A in step 211.

For example, if a recipient is selected from a list of contacts provided by messaging or e-mail applications by touch and drag events on the current screen, which is the screen through which the controller 110 runs a message application after hiding the screen window A, then the memo data executed on the screen window A may be stored as data for the recipient, or may be stored as attached data in a message or e-mail that is sent to the recipient after the controller 110 automatically switches to a message/e-mail mode or switches to the messaging or e-mail applications. For example, if a date is selected from a list of dates provided by a calendar application by touch and drag events on the current screen on which the controller 110 runs the calendar application after hiding the screen window A, then the memo data executed on the screen window A may be stored as data corresponding to the selected date.

As another example, if an icon representing a type of an application, such as a message application, e-mail application and an album application, is selected by touch and drag events on the current screen for which the controller 110 is in an standby mode after hiding the screen window A, then the memo data executed on the screen window A may be stored as attached data after the controller 110 switches to a message or e-mail mode, or the memo data may be stored as data corresponding to an image selected from the album.

While hiding the screen window A in step 206, the controller 110 updates applications installed in the mobile terminal in step 212. More particularly, in step 212, the controller 110 updates synchronizable applications, and may update the applications only if their synchronization time is longer than a time period starting from a time at which the screen window A was displayed until a time at which the screen window A was hidden. While displaying the screen window A, the controller 110 may update the applications, or the controller 110 may update the applications only when the screen window A is exited.

For example, when the mobile terminal is set to update an application only in the state where the screen window A is hidden, if the screen window A for running a memo application is displayed so as to overlap with the current screen of a messenger application that is currently running, then the controller 110 does not update the application. Thereafter, if the screen window A is hidden, then the controller 110 compares a synchronization time for the messenger application with a time period from when the time the screen window A was displayed until the time when the screen window A was hidden, in order to update the synchronizable messenger application. For example, if a synchronization time for the messenger application is set as ‘5 seconds’ and a time period from the time when the screen window A was displayed until the time when the screen window A was hidden is ‘3 seconds’, i.e., the synchronization time for the messenger application, that being 5 seconds, is longer than the time period from when the time the screen window A was displayed until the time when the screen window A was hidden, that being 3 seconds, then the controller 110 updates the messenger application. For example, the controller 110 may display the conversations made while the screen window A is seen, thereby preventing the update from frequently occurring every time the screen window A is hidden.

If updating of the application is set to occur in the state where the screen window A is hidden, then the controller 110 may update the synchronizable messenger application and display it on the background screen when displaying the screen window A, which is for displaying the memo application, on the current screen in an overlapping manner.

If updating of the application is set to occur only when the screen window A is exited, then the controller 110 may update the synchronizable messenger application and display it when the screen window A is completely exited and while displaying the screen window A on the current screen displaying the messenger application in an overlapping manner.

While displaying the screen window A in step 202, the controller 110, in step 213, determines whether an exit button, key or input is selected on the screen window A. If the exit button, key or input is selected on the screen window A, the controller 110 exits or stops displaying the screen window A in step 214.

The operation of displaying and hiding the screen window in response to the touch event in FIGS. 2A and 2B will be described with reference to FIGS. 3A to 7B.

FIGS. 3A to 3C illustrate a process of running a memo application during Internet access in a mobile terminal according to an exemplary embodiment of the present invention.

Referring to FIGS. 3A to 3C, while the user views an article, image, video, or website over the Internet, as shown in FIG. 3A, if a touch event to run the memo application occurs on the screen displaying the article, regardless of the area at which the touch event occurs on the screen, then a separate window may be displayed by overlapping a screen window 161 for running the memo application on the current screen displaying the article, as shown in FIG. 3B. While displaying the screen window 161, if a touch event (i.e., a touch input) occurs and is maintained in an external area of the screen window 161 on the entire screen, then the screen window 161 may be hidden, as shown in FIG. 3C, allowing the user to view the current screen displaying the article. While hiding the screen window 161, as shown in FIG. 3C, if the touch event having occurred is terminated, then a separate window may be displayed again so as to overlap the screen window 161 on the current screen, as shown in FIG. 3B.

Referring to FIGS. 5A to 5D, in a standby mode, as shown in FIG. 5A, if a touch event to run a memo application occurs, then a separate window is displayed so as to overlap the screen window 161 for running the memo application on the standby mode screen as shown in FIGS. 5B and 5C.

While displaying the screen window 161, as shown in FIGS. 5B and 5C, if a touch event occurs and is maintained in an area of the screen other than the area displaying the screen window 161, then the screen window 161 is hidden and the standby screen is displayed, as shown in FIG. 5D. If the touch input having occurred is terminated while in the state shown in FIG. 5D, then the screen window 161 is again displayed, as shown in FIGS. 5B and 5C.

If updating of the application is set to occur only in the state where the screen window 161 is hidden, then updating of a time widget from a displayed time of ‘07:11’ to the current time ‘07:12’ is not performed while the screen window 161 is displayed, as shown in FIG. 5C. If updating of the application is set only to occur when the screen window 161 is exited, updating the displayed time of ‘07:11’ of the time widget to the current time ‘07:12’ is not performed even while the screen window 161 is hidden, as shown in FIG. 5D.

FIGS. 6A and 6B illustrate a process of running a memo application during use of a message application in a mobile terminal according to an exemplary embodiment of the present invention.

Referring to FIGS. 6A and 6B, if a touch event corresponding to executing a memo application occurs on a current screen displaying the message application, then a separate window is displayed by overlapping the screen window 161 for running the memo application on the current screen displaying the message application, as shown in FIG. 6A. While displaying the screen window 161, as shown in FIG. 6A, if a touch event occurs and is maintained in an area of the screen other than the area displaying the screen window 161, then the screen window 161 is hidden and the current screen displaying the message application is displayed, as shown in FIG. 6B.
